Whether the examination process of Shanghai Eye Hospital requires fasting in advance

Shanghai Eye Hospital is a medical institution specializing in the treatment of ophthalmic diseases, providing a variety of services including ophthalmic examinations. Many patients will be concerned about whether they need to have an empty stomach in advance before seeing a doctor. Here are some aspects to explain this problem.

1. Pupil dilation test

The first aspect of the author is the examination of pupil dilation, which is a common means for ophthalmologists to carry out detailed fundus examinations. Pupil dilating drugs can dilate the pupils, which is convenient for doctors to observe fundus conditions. Generally speaking, this kind of examination requires fasting in advance, because the digestive system will secrete gastric acid after eating, which may affect the absorption of mydriasis drugs, thus affecting the accuracy of the examination. In addition, fasting in advance can also avoid nausea, vomiting and other uncomfortable symptoms during the examination.

However, not all pupillary dilation tests require fasting in advance. For example, if it is a simple pupil dilation test, such as the use of children's eye patches, it is generally not necessary to fasting in advance.

2. Blood examination

The second aspect is blood examination, which is a routine examination before medical treatment. Blood examination can help doctors understand patients' health status and provide basis for determining treatment plans. For most blood testing items, there is no requirement for fasting in advance. However, for some special test items, such as blood sugar, cholesterol, etc., there may be a reminder to ask for an empty stomach. Therefore, please consult the hospital staff for specific requirements before seeing a doctor.

3. Corneal topography examination

The third aspect is corneal topography, which is a commonly used ophthalmic examination to assess the shape and curvature of the eye surface. According to the experience of Shanghai Eye Hospital, corneal topography examination usually does not require fasting in advance. This is because this examination method is non-invasive and has no special requirements for diet. However, in order to ensure the accuracy of the examination results, patients need to keep their eyes clean and follow the doctor's specific instructions to avoid unnecessary interference during the examination.

4. Intraocular pressure test

*The latter aspect is intraocular pressure measurement, also known as intraocular pressure measurement. Intraocular pressure (iop) is an important indicator of eye health. It is not necessary to have an empty stomach in advance for intraocular pressure examination, but it is better to avoid strenuous exercise and smoking before medical treatment, because these will affect the normal measurement of intraocular pressure.

summary

To sum up, in the examination process of Shanghai Eye Hospital, not every examination requires fasting in advance. According to different examination items, patients need to follow the corresponding requirements. * Ask the hospital staff for specific requirements before going to the hospital to ensure the accuracy and safety of the examination.
